Which expression is equivalent to StartFraction b Superscript negative 2 Baseline Over a b Superscript negative 3 Baseline EndFr
nignag [31]

Answer:

  • \frac{b^{-2}}{ab^{-3}}=\frac{b}{a}

Step-by-step explanation:

Writing the description in algebraic translation

\frac{b^{-2}}{ab^{-3}}

so we have to find the expression which will be equal to \frac{b^{-2}}{ab^{-3}}.

Considering the expression

\frac{b^{-2}}{ab^{-3}}

\mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}=x^{a-b}

\frac{b^{-2}}{b^{-3}}=b^{-2-\left(-3\right)}

so the expression becomes

=\frac{b^{-2-\left(-3\right)}}{a}            ∵ \frac{b^{-2}}{b^{-3}}=b^{-2-\left(-3\right)}

\mathrm{Subtract\:the\:numbers:}\:-2-\left(-3\right)=1

=\frac{b}{a}

Therefore,

                    \frac{b^{-2}}{ab^{-3}}=\frac{b}{a}
